CLOUD COMPUTING DRIVING FACTORS
64
Offsite
IT resources are accessed from an offsite data center that is not owned by you; thus yielding in cost of ownership, licenses etc.
Virtual
Software stacks of databases, web servers, operating systems, storage, and networking are assembled virtually and accessed via the web.
On-demand
Use as needed, resources can be turned on or off quickly and as needed including storage capacity, data bases, web servers and operating systems.
Pay-per-use
Pay for what you need, not for unneeded capacity.
Simple
Resources can be configured quickly and easily, e.g. leading Cloud computing platforms have open API’s.
Scalability
Access to extremely large infrastructure that would be challenging to build as a single entity.
Storage Capacity
The use of Cloud computing for storage capacity can be ideal, especially for spikes in usage. Because the use of the cloud entails low or no upfront capital cost and low ongoing operational costs, the ability to take advantage of pools of resources on demand in real‐time can yield business advantage.
Elasticity and Resizability
Ability to be highly flexible – nearly instantaneously – to changes in load. With Cloud computing, an infrastructure supporting an application, business, or business process can be easily resized and rightsized, depending upon conditions
Collaboration
Shared environment, IT resources can be consolidated, many users share a common network, allowing costs to be managed
